BED-S PRING.

SPECIFICATION forming part of Letters Patent No. 406,475, dated July 9,1889- Serial No. 259,955. (No model.)

To all 1071,0723, it may concern:

Be it known that I, CHARLES'E. Bron, a citizen of the United States,residing at J onesburg, in the county of Montgomery and State ofMissouri, have invented a new and useful Improvement in SpringBed-Bottoms, of which the following is a specification.

My invention relates to an improvement in twin bed-springs; and itconsists in the peculiar construction and'arrangement of parts, thatwill be more fully set forth hereinafter, and particularly pointed outin the claims;

In the drawings, Figure l is a plan view of a bed-bottom having springsembodying my invention. Fig. 2 is a side elevation of one of my improvedtwin springs. Fig. 3 is a perspective view of the same. i

From a wire D, of suitable length and size, a pair of inverted conicalcoils d d are formed. From the upper end of one of the coils extends aZ-shaped connecting-frame (Z the arms act which are longitudinal andarranged beyond opposite sides of the tops of the coils and parallelwith each other. The portion e of the wire which connects the arms 6 isarranged obliquely between the tops of the coils, and thereby bridgesthe space between the said tops of the coils and the arms 6. One of saidarms 6 is much longer than the other and extends outward in alongitudinal direction beyond the proximate coil d, and has its outerend bent obliquely at an acute angle to form the portion 6', whichmerges in the top of the coil d. The said portion e and the projectingportion 6 constitute an open acuteangled frame G. At the lower ends ofthe coils the ends of the wire are bent to form inwardly-extendingclamping-arms F and spring-coils f whereby the lower ends of the springsare adapted to be secured to the transverse slats C of abedstead, asshown in Figs.

1 and 2.

The advantages resulting from my construction of the bed-spring are asfollows: The longitudinal arms 6. of the frame, which connect the topsof the coils ,being disposed beyond the opposite sides of the coils, thesaid frame is rendered wider than the coils, and the portion e whichconnects the said arms, being arranged obliquely between the coils andacross the space between them, the tops of the said coils are entirelyunobstructed,

and the same are adapted to clear the connecting-frame when the springis weighted. Consequently the tops of the coils are caused to rise inthe open portionof the frame until they come in contact with the bottomof the mattress, and the springs are provided with a maximum amount ofbearing or supporting surface and adapted to be made from a minimumamount of wire. Inasmuch as the connecting-frame is thus caused to clearthe tops of the spring-coils, it follows that no two parts of the twinspring come in frictional contact when the same is weighted, andconsequently there is no abrasion on any portion of the wire, thesprings are rendered noiseless, the durability thereof is veryconsiderably enhanced, and the tick which covers the mattress is notliable to be clamped between parts of the spring and cut or worn intoholes.

My springs are arranged transversely on the slats and longitudinallywith relation to the bedstead, and each pair of springs is arranged inreverse relation to each other with their coils d proximate, as shown inFig. 1, and thereby their acute-angled frames or portions G are causedto overlap each other and to lie in the same horizontal plane and bridgethe'space between the pairs of springs, the oblique sides a of saidframes or portions being arranged parallel with each other, and hencethe mattress is prevented from sagging between the said pairs ofsprings.

, Having thus described the invention, I claim 1. The bed-spring formedfrom a single piece of wire and comprising the twin spiral coils, theZ-shaped connecting-wire between the upper endsthereof, saidconnecting-wire being bent to form the parallel longitudinal portions 6on opposite sides of the top of the coils the obliquely-arranged portion6 connecting the parts e and arranged to bridge the space between thetwin springs,'one of the side portions 6 projecting longitudinallybeyond one of the coils and being then bent to form the oblique portion6', which merges in the top of the coil and diverges from the portion 6said portions 6, c and e being arranged in the same horizontal planeabove the tops of the coils, substantially as described.

the Z-shaped connecting portion between 2. The twin springs comprisingthe coils,

their tops, and the acute-angled arm projecting longitudinally from thetop of one of the coils and arranged in the same horizontal plane Withthe connecting portion, whereby, when the pairs of said springs arearranged in the same longitudinal line and in reverse relation to eachother, the acute-angled arms will lap in the space between the proximatecoils, with their oblique portions parallel, and

bridge the said space, substantially as de- 10 scribed.

In testimony that I claim the foregoing as my oWn I have hereto affixedmy signature in presence of two Witnesses.
